Help Upgrading

When I run 3.52 m33 firmware creator it says
file 150.pbp couldn't be opened press x to exit

Why is this the file is in the folder m33 creator and I have renamed it to 150.PBP

I'm on 3.40 oe currently

Try taking the.pbp part off and then run it, it may already be recognized as a .pbp, and do the same for the 3.52 update.

Your a legend it worked I don't no why it already reconnized them as PBP files though
